RODI Question

[Echomsp]

I'm in the process of converting my tank from freshwater to saltwater, but plan on making the conversion once my new house is built. For now I have freshwater fish in my tank and was curious if RODI would be harmful to use in freshwater. Someone mentioned that I may be filtering out beneficial nutrients for a freshwater tank.

I recently purchased the RODI filter (thanks, Bruno516 !)and was looking to go ahead and get it running to make sure it's working properly. Also, if there is a different site that would be better to ask, please let me know.

Thanks!

Yes you can use it but it’s best to add something like this first before using in freshwater tanks.

Perfect, thanks!

What kind of fish, and how hard is your water?

It's always fine for topoff, but tap (conditioned if needed) is usually fine, if not better.

You don't want to use just RODI, but usually just mixing it with tap water is enough. It really just depends on the species you are keeping.

If you look at the ingredients in the RO conditioners like the one pictured, it is mostly the same chemicals found in the water analysis provided by your town's water provider.

The water is soft, I'll test it this evening, but we have never had hard water here.

I can't even name them, most came with the tank. Maybe a picture is best.


Beside what you can see, there is a bichir, rope fish, and a few of these:



There's about 300 gallons total in the system, I would be topping off about 30g/week and the same in water changes.

I'm getting the impression that I'm going to be pouring money down the drain and I should just wait until I do the conversion before running the filter.

Last pic is a red tail botia and the reddish fish at the top of the pic is a serpae tetra. I wish I could have a 300gal freshwater tank.

Angels, loaches, tetras, danios, etc are all fine with your dechlorinated (or not chlorninated in the first place) tapwater.

Many discus keepers and wild angel keepers use ro but add back trace minerals
